ASP.NET/HTML: HTML button's onClick property inside ASP.NET (.cs)
You can do that on any server control and this button is made a server control by defining "runat=server". The problem is probably in your definition of the event:
<button ... runat="server" ... onServerClick="btnLogin_Click" />You don't need "();" there...
Apart from that can you explain why you don't use the <asp:Button> here because I don't really see a problem with that...
You'll want to use the onServerClick. There's an example of how to do that on MSDN:
<button id="Button1" OnServerClick="Button1_OnClick" runat="server"> Click me!</button>protected void Button1_OnClick(object Source, EventArgs e) { // secret codes go here}
btnLogin.Click += new EventHandler( btnLogin_Click );
will assign the btnLogin_Click event handler to the button's Click event.
however, I would point out that assigning a handler in the markup of the aspx page does not "expose your codes", as the HTML rendered down to the client doesn't have any of that information in it.
